23.4.2. Modulation Data Source
The transceiver may be configured to obtain its modulation data from one of three different sources: FIFO
mode, Direct Mode, and from a PN9 mode. In Direct Mode, the TX modulation data may be obtained from
several different input pins. These options are set through the dtmod[1:0] field in "Register 71h. Modulation
Mode Control 2".
23.4.2.1. FIFO Mode
In FIFO mode, the transmit and receive data is stored in integrated FIFO register memory. The FIFOs are
accessed via "Register 7Fh. FIFO Access," and are most efficiently accessed with burst read/write opera-
tion.
In TX mode, the data bytes stored in FIFO memory are "packaged" together with other fields and bytes of
information to construct the final transmit packet structure. These other potential fields include the Pream-
ble, Sync word, Header, CRC checksum, etc. The configuration of the packet structure in TX mode is
